  1.         'Get the length of characters in the text box
  2.         Dim textBoxLength As Integer = TextBox1.Text.Length
  3.  
  4.         'Format the textbox character length by dividing by 11 (phone number length) and subtracting 1 (total number of commas to add)
  5.         Dim textLength As Integer = textBoxLength / 11 - 1
  6.  
  7.         'Make i an integer which is equal to the textLength variable.  This is not necessary, just pretty
  8.         Dim i As Integer = textLength
  9.  
  10.         'Loop in reverse order, inserting a comma every 11th character
  11.         'We are looping backwards since the length of the textbox text changes with every insertion
  12.         Do Until i = 0
  13.             TextBox1.Text = TextBox1.Text.Insert(11 * i, ",")
  14.             i = i - 1
  15.         Loop
